Second hand furnish, car... (Brasilia)

Hello. I will come in Brasilia at the end of august, with my family (2 little children : 3 years, 6 months), and we will look for flat, school and everything. I've been looking for the diferent post son those subject. Thanks for the ideas, and advices.

About housing, I was wondering if it was possible to buy staff (furnish, bed, table...) for the house in second hand, from people moving and living brasilia. Is there a site, or net, where people send offers of that type ?
